A Maryland man dressed in camouflage killed a multimillionaire at a nursing home, police said

A Baltimore man is accused by police of hiding and shooting a millionaire at a nursing home on Valentine’s Day and later shooting at a Maryland state trooper during a traffic stop.

Maurquise Emillo James, 22, who goes by “Malquazy,” was charged with first-degree murder in the Feb. 14 killing of Robert Fuller Jr., 87, according to police charging documents.

James was also charged with attempted murder, aggravated assault, use of a firearm during a violent conflict, and charges related to the alleged shooting of a police officer on Tuesday, which seriously injured him, documents said.

What investigators don’t have is a reason.

Fuller lived at the Cogir Center for the Elderly in Potomac, Maryland, where James worked as a night medical technician, according to the documents.

“We don’t know exactly why he shot and killed Mr. Fuller,” Montgomery County Police Captain Sean Gagen said at a press conference Wednesday. “When he spoke to him, he said that their relationship was very good and that he would not hurt Mr. Fuller.”

But the police said that when they searched the suspect’s house, they found many wigs and a mask.

James was being held Thursday at the Montgomery County Correctional Facility, jail records show.

Fuller, a retired Navy Reserve officer who donated millions of dollars to charities in Augusta, Maine — where he worked as an attorney — was found shot in the head in the apartment he shared with his partner, according to court documents.

Under questioning, the partner told detectives that James gave Fuller his usual dose of the pain reliever Oxycodone on the night of Feb. 13.

But the partner, who is not identified in the charging documents, said James returned later and asked Fuller if the drug had “started to kick in.”

The partner told detectives that was “weird” because James did not return after giving Fuller his medication.

When told that Fuller had been shot, the co-worker expressed surprise that the shooting did not wake them up because “his hearing was very good,” court documents said.

James confirmed that he gave Fuller his medication and continued to work at the facility while detectives investigated Fuller’s murder.

Later that day, detectives obtained surveillance footage from 5 a.m. that showed a person wearing what appeared to be a mask and wig, and a “distinctive” jacket, walking toward a side door of the building that was rarely used.

This person was seen opening the door and entering the stairs.

About 12 minutes later, charging documents say, the same person was seen walking out the door and “running down the street.”

Investigators later discovered that the door had been opened with a rolled up paper towel and the battery had been removed from the sensor that would have set off the alarm.

They also began to suspect that the murder may have been an inside job, because whoever killed Fuller “had access to the building,” court documents say.

Last week, on February 20, police released a short clip of surveillance video and a press release noting the suspect’s “unusual movement” and the jacket.

On Sunday, the vise around James began to tighten after an anonymous tipster told police that the person in the video was walking normally and might work at the facility, according to charging documents.

Then on Monday night, the director at Cogir noticed that James was still there long after his shift ended and asked him why he was still there.

“James then immediately took his belongings and left,” the court documents said. At 3 a.m. Tuesday, a state trooper pulled over a “silver Infiniti sedan with no tags.”

When the army began to approach the car, the driver “shot at the army” and took off. The army did not return fire.

Police arrested James Tuesday afternoon in Rockville, Maryland for shooting at a trooper, Gagen said. He was later charged with murdering Fuller after a similar shell from the soldier’s shot to the gun used to kill the old man.
